The Africana Studies and Research Center (ASRC) at Cornell University is an academic unit devoted to the study of the global migrations and reconstruction of African peoples, as well as patterns of linkages to the African continent (and among the peoples of the African Diaspora). The Africana Studies program offers around 23 graduate and undergraduate courses each semester. Africana offers an undergraduate major for students in the Cornell University College of Arts and Sciences as well as a Ph.D through the Cornell University Graduate School. The John Henrik Clarke Africana Library, located at the Center, focuses on the social, economic, and political dimensions of the history and cultures of peoples of African descent. It has more than 17,000 volumes.
